Specification of Letters Patent.

Application filed October 11, 1907. Serial No. 396,987.

To all whom it may concern:

Be it known that I, ELnoNon Jossrn JOLIVET, a citizen. of the French Republic, and resident of Paris, France, have invented certain new and useful Improvements in Vibration-Neutralizers, of which the following is a specification.

- This invention has for its object a kind of elastic plates or bands intended to be interpo ed between e f amework of engines and their solid foundations or arranged beneath these foundations with a view of doing away with the trepidations and vibrations resulting from their motions.

n the annexed drawing, given only by way of demonstration, Figure 1 is a vertical section of a fragment of elastic plates, and Fig. 2 is a top p an-view of Fig- 1) A plate or elastic band constructed according to the present inventioncomprises a mattress a having arallel faces made of felt, hair, cork or other similar product arranged between two plates 1) of agglomerated cork; the whole being arranged between two plates of sheet metal 0, c the edges of which are bent as shown by the Fig. 1 in order to surround the other parts or elements on a part of their height. Inside the mattress to are arranged s )rmgs d the strength and the number of w rich vary according to the weight to be su )portcd. The felt (I or simi lar material is impre nated with a material such as heavy oil or the like according to the applications of the device. Attaching devices 0 made of metallic Wire and distributed in a suitable manner upon the surface of the elastic plate connect the lates of sheet metal 0 so as to ren der soli a l-y all the elements of the elastic plat e. he plates of sheet metal simply have as their object to of the massive structure, the liquid elements of the masonry such as mortar, the plaster and the like from flowing into the interior of the mattress a which, as will be easily understood, would be injurious for the elasticity of the said material. The thus constituted plate may be arranged under the massive masonry or between two parts of this massive masonry 'or still between the engine and the said masonry; it may also be arranged in moist places or even in the for impregnating the felt will preferably be tallow andin all the cases the fatty material protects the springs against oxidation and allows of them being employed during a very long space of time. The shape of these sprin gs may vary. The drawing shows coiled springs but conical spiral springs may equally be employed in case it is desired to obtain a greater suppleness as thiskind of springs allows a greater yielding than the coiled springs. These elastic lates may be used in solid masonries of all kind of engines especially of steam hammers, rams, presses, motors of any kind, dynamos and the like; they are adapted to attenuate and even to suppress the trepidations adapted to disturb the neighbors.

Having now fully described my said invention what I claim and desire to secure by Letters Patent is 1. In an antivibration plate of the kind described the combination of a plate of elastic material, elastic members inserted into the said plate of elastic material and backing plates for both sides of the said plate and means for connecting all together, substantially as and for the purpose set forth.

2. In an antivibration plate of the kind described, the combination of a plate of elastic material, springs inserted into the said late of elastic material and extending therein to the surfaces of the plate, backing plates for both sides of the said plate, rigid backing plates for the said backing plates and means for connecting the whole together, substantially as and for the purpose described.

3. In an anti-vibration plate of the kind described the combination of a plate of elastic material, coiled springs inserted into. the said plate and exten ing therein to both the surfaces, backing plates of agglomerated cork for both surfaces of the said plate, rigid backing lates of sheet metal for each of the said backing plates and means for securing the whole together, substantially as and for the purpose set forth.

4. In an anti-vibration plate of the kind described the combination of a plate of elastic materialimpregnated with a fatty substance, springs inserted into the said plate and extending to both surfaces thereof, backing plates of agglomerated cork for both surfaces of the said plates of sheet metal or each of the said late, rigid backing gether, substantially as an backing plates and means for connecting the whole together, substantially as and for the purpose set forth.

5. In an anti-vibration plate of the kind described the combination of a plate of elastic material impregnated with heavy oil, springs inserted into the said plate and extending to both surfaces thereof, backing lates of agglomerated cork for both suraces of said plate, rigid backing plates of sheet metal for each of said backing lates and means for connecting the who e tofor the purpose set forth.

6. In an anti-vibration plate of the kind described-the combination of a plate of elastic material impregnated with a water repelling substance, s rings inserted into the said plate and exten ing therein to both surfaces thereof, backing plates of agglomerated cork for both surfaces of said plate, rigid backing plates of sheet metal for each of said backing plates and means for securin the whole together, substantially as and or the purpose set forth.

7. In an anti-vibration plate of the kind described the combination of a plate of elastic material such as felt impregnated'with a fatty substance, of springs inserted into the said plate and extendin to both surfaces thereof, a backing plate ofagglomerated cork for both surfaces of said plate, a rigid back-- ing plate of sheet metal ap lied to each of said backing plates and havin bent borders and attaching devices made 0 metallic wire and ada ted to secure the whole together, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand in, resence of two witnesses.
